Do those small utility boxes alongside the tracks make sense for fiber optic? I expected things like that to be larger, if only because fiber has a minimum bend radius.
Edit: Good article though, I enjoyed it a lot.
- adamcharnock 11mo agoThe min bend radius isn’t that large in my experience. On the order of 10cm IIRC, possibly even less.
- st_goliath 11mo agoMuch smaller than that, some might even say a utility box is overkill: https://old.reddit.com/r/techsupportgore/comments/nvwcuh/the_fiber_line_coming_into_my_village_in_korea/ https://old.reddit.com/r/techsupportgore/comments/nvwcuh/the...
- Lukas_Skywalker 11mo agoEven less is correct: outdoor fibers (G.652.D) have a minimum bend radius of about 30mm. The indoor counterpart (G.657.A1 and A2) have 10mm and 7.5mm.
- lesuorac 11mo agoThose are more of a technically no? Like I have fiber to the house and you really need to pinch it and whatnot to cause an internet outage.
- oarsinsync 11mo agoA small bend radius means it can have a tight bend. A large bend radius means it has to be a big bend. A 7.5mm bend radius is really small. You can bend that stuff pretty tight before you create a problem.
- eqvinox 11mo agoThe larger cables tend to have strength members with higher physical bend radius restrictions, i.e. you can't bend the steel or kevlar elements that tightly without breaking things.
- mikeyouse 11mo agoFiber’s perfectly happy being joined in 12” by 16” boxes for small runs. The terminal box in my garage has a few loops and is more like 6” x 8”. https://www.seeclearfield.com/fiber-optic-wall-box/metal-wall-boxes/outdoor-wall-panels.html https://www.seeclearfield.com/fiber-optic-wall-box/metal-wal...
- whatsupdog 11mo agoRailroad minimum bend radius is orders of magnitude bigger than fiber's.
